To taf/ZZ whom may cor/warn:

Be it known that I, JOSEPH M. WERTH, a

citizen of the United States, residing at Elk-- horn, in the county ofMcDowell and State of West Virginia, have invented new and usefulImprovements in Pipe-Couplings,of which the following is aspecification.

This invention relates to pipe-couplings; and the objects of theinvention are to provide a simple and eflcient device of this characterwhich can he easily applied and as readily removed Without the use ofpipe-Wrenches, as it is not threaded lonto the adjacent ends ofcontiguous pipesections. It can be used upon old pipes having threadswhere the same are Worn and will effectually unite the same withoutpossibility of leakage, it canbe ap plied under water or in closeplaces, it is especially well adapted for uniting temporarily-laidpipes, and'it costs but a trifle more than a plain coupling.

The improved pipe-coupling includes in its construction a plurality ofsections, one of which has Wedge faces .transverse to each other and theother of which is provided with key-holding means in connection 'with akey also having wedge-faces transverseto each other and adapted tocooperate with the other Wedge-faces, so that when the key is drivenhome the coupling will be firmly clamped in place and will bind a gasketor packing surrounding the' adjacent ends of pipe-sections firmly inplace. In the present case one of the sections of the coupling has aprojection upon which the said'wedgefaces first mentioned are formed,While the other section is furnished With loops for receiving thekey,and between which when the coupling is in its effective position thesaid projection is disposed.

The invention includes lfurther objects and advantages which, with theforegoing, will be set forth in the following description, while thenovelty thereof will form the basis of the claims succeeding suchdescription, and said invention is clearly shown in the accompanyingdrawings, forming, a part of this specification, and in which- Figure lis a plan view of the improved device in its working condition. Fig. 2is a similar view of the same with the sections pen.

Fig. 3 is a perspective View of the lo king- 1key.v Figs. Lland 5 arerespectively transverse and longitudinal sections of the device.

Like characters refer to like parts in all the figures of the drawings.

j with the substantially perpendicular loops 5,

adapted to receive a locking-key, hereinafter more particularlydescribed, and these loops may or may not he integral with the partcar-y rying the same.

The section lis providedupon its upper side with a projection 6, whichmay or may not, as is the case with the loops 5, be made -in one piecewith the coupling-half to Which it is secured. Strengthening ribs orfins 7 extend laterally from the said projection. The sides of theprojection are in contact, or substantially so,with the ad jacent facesof the loops 5, so as to secure the projection'firmly in place.

The projection 6 has upon its upper side a wedge-face S and terminatesin a vertical lug 9 upon said upper side, said lug having upon its innerside a Wedge-face l0, which, it will be seen, is situated at rightangles to the other wedge-face, and these wedge-faces are adapted tocooperate with similar wedge-faces, hereinafter more particularlydescribed, upon the locking-key 11.

The coupling, with the parts carried thereby, may be made of anysuitable material, and the internal diameter of the coupling,r issomewhat greater than the external diameter of the pipe-sections whichit unites, so that a gasket fitted around said pipe-sections can beaccommodated within the coupling. The wedge-key il may also be made ofany suitable material. Said key, which is adapted when in its workingposition to fit between the loops 5, has upon its under side a wedgefacel2, adapted to cooperate with the Wedgeface lud an undercut-out portion13, which thereby forms a shoulder 14, said undercut portion, it beingseen, being situated at the reduced end ofthe Wedgekey. The shoul- 5 der14 has upon its outside the Wedge-face 15,

adapted to coperate With the Wedge-face 10.

In use a gasket of sheet lead, rubber, or any other suitable materialaround the adjacent sections of pipe, after j o which the coupling isplaced around the gasket and drawn tightly therearound, with theprojection 6 disposed between the loops 5. The reduced end of theWedge-key 11 is then introduced into one of the loops 5 and ad- 5 vancedtoward and into the other loop. This will bring the Wedge-faces S andand 12 and 15 into contact. The Wedge-key is then driven home by asuitable implement, so as to constrict the coupling upon the pipe, and

o thereby bind the gasket securely in place and .5 rely on theseWedge-faces to prevent accidental removal of the key, but provide thesecond pair ot wedge-faces 8 and 12 to secure this result, which pairsof Wedge-faces, it will be seen, are disposed transversely and subostantially at right angles to each other, by

virtue of Which it is practically impossible for the key to beaccidentally dislodged When it is driven home.

The grooved portion 4, hereinbefore re- 5 ferred to and Which receives abead upon the pipe, serves to prevent longitudinal movement of thesections of said pipe When the same are coupled.

The invention is not limited to the exact o construction hereinbeforeset forth,formany variations may be adopted Within the scope of thefollowing claims, and said pipe-coupling may be used in many other Waysthan those indicated herein.

5 Having described the invention, what I claim is- 1. A pipe-couplinghaving a plurality of ledge-faces disposed transversely to eachV'/other, a locking-key for securing the pipeo coupling in place alsohaving Wedge-faces is Wrapped disposed transversely to each other andcooperative With said other Wedge-faces, and means for holding the keyin place.

2. A pipe-coupling having a plurality orf hinged sections one of Whichhas Wedge-faces disposed transversely to each other, key-holding` meanson the other section, and a key, said key having wedge-faces disposedtransversely to each other and coperative with said other wedge-faces.

3. A pipe-coupling comprising a plurality of hinged parts, one of whichis provided With a plurality of loops, and the other of which has aprojection furnished with Wedge-faces disposed transversely to eachother, and a key held in place by said loops and having Wedgefaces alsodisposed transversely to each other, and adapted to coperate with saidother Wedge-faces.

4. A pipe-coupling having a plurality of loops and a projection adaptedto fit between said loops and movable relatively thereto, saidprojection having wedge-faces disposed transversely to each other, and akey adapted to enter said loops and having wedge-f aces also disposedtransversely to each other and coperative with said other Wedge-faces.

5. A pipe-coupling comprising a plurality of sections, one of which isprovided with a plurality of loops, and the other of which is furnishedwith a projection, said projection having a wedge-face and a lug uponits upper side, and the lug having upon its inner side a Wedge-facedisposed transversely to the other Wedge-face, and a key adapted to beheld in place by said loops and having a Wedge-face upon its under sideadapted to engage said first-mentioned Wedge-face, said key having anundercut portion at its reduced end, thereby forming a shoulder, andsaid shoulder having a wedgeface coperative with the Wedge-face on saidlug.

In testimony whereof I have hereunto set my hand in presence oi' twosubscribing Witnesses.

JOSEPH M. WERTH.
